Are the natives of America mongoloids?

Answer 1

Under that racial classification, yes, at least most of them are. Native Americans descended from somewhere around the Altai mountains. Altai people are Mongoloids.

The Arctic Americans are neo-Mongoloid, and are recent arrivals from Asia.

However, it may not be a good idea to classify people based on Mongoloid/Australoid/Negroid/Caucasoid/Capoid, as the system is arguably outdated.

Answer 2

in the north of India, they tend to be a mix of caucosoid and mongoloid and in south of India they tend to be a mix of caucosoid and austroloid.
